WHAT TO DO IN CASE OF TROUBLE
l
Notify appropriate personnel. (If the system is connected to the city, notify the fire department monitoring facility.)
l
Unlock and open panel door.
l
If tone device is sounding, set TROUBLE SILENCE switch (Fig. 27 on Page 24) to its down position.
Note: When the trouble has cleared, the tone device will sound again as a reminder to set the TROUBLE
SILENCE switch back to its normal position.
Corrective Actions
l
Observe TROUBLE indicators and perform the corrective action outlined in Table 5 (see Page 27).
l
When the trouble clears, set TROUBLE SILENCE switch to its NORMAL (up) position.
l
If trouble is on the panel’s circuit board, contact your local Simplex Branch Office (listed in the Yellow Pages under
Fire Alarm).
Important: Any attempt to replace any components on the panel’s circuit board voids the warranty.
CAUTION: 24VDC exists at control panel circuit board. This voltage may cause damage to equipment during fuse
replacement, resistance measurements, or wire checks. When performing these activities, ensure that
the battery jumper (white wire) is disconnected from the battery and that all AC power is removed from
the system’s panel and peripherals. When replacement or checks are complete, restore power (AC
power first then batteries) and press RESET switch until the zone LEDs illuminate.
Note: When checking a suspected circuit, remove the circuit from the panel terminals (see Page 10, Building Wiring
Checkout Procedure), and the system wiring diagram (841-610) provided with the panel.
ALARM VERIFICATION FEATURE (OPTIONAL)
The 4001 Fire Alarm System can be programmed for alarm verification (see Page 20, System Programming).
l
Alarm verification works on/y with Simplex smoke detectors.
This feature requires the verification of any alarm initiated by a smoke detector, but allows contact devices (heat
detectors and manual stations) residing in the same zone to initiate alarms upon activation. The feature works as
follows:
a. If a smoke detector senses an alarm, the 4001 starts a 30-second timer, but otherwise ignores the alarm.
b. If, during the 30 seconds, no contact device in any zone (or smoke detector in another zone) activates, the zone
enters a 15second reset cycle.
c. Following the reset cycle, the 4001 enters a 120-second confirmation period. If, during this period, the smoke
detector re-alarms (or another smoke detector in the same zone initiates an alarm) the 4001 alarms immediately.
d. If no alarms occur during the 120-second confirmation period, the 4001 automatically returns to normal operation.
Notes:
1. If, at any time during the above time period, a smoke detector in another zone (or contact device in any zone)
activates, the 4001 alarms immediately.
2. If Zone 1 is used with the coded input option, then alarm verification will not work on Zone 1.
3. If Zones 3 and 4 use the sprinkler/water-flow options, then alarm verification will not work on Zones 3 and 4.
